AGNES MAOFADYEN, OF PONOA, OKLAHOMA TERRITORY.

HEAT-RADIATOR.

SPECIFICATION forming part of Letters Patent N 0. 765,052,

Application filed October 19, 1903.

To all whom it may concern:

Be it known that I, AGNES MACEADYEN, a citizen of the United States,residm'g at Ponca,

county of Kay, andTerritory of Oklahoma,

have invented certain newand useful Improvements in Heat-Radiators, ofwhich the following is a specification.

The object of my invention is toprovide a radiator or heating-drum whichmay be connected with a stove and receive therefrom the products ofcombustion, which while passing through the drum will heat it and causeit to radiate heat, which will largely increase the heat of the room inwhich it is placed, whether it be in thesame room with the stove or in aseparate room. 7

My improved radiator differs from others of this class in that it is soconstructed that the soot which inevitably collects on it may be easilyremoved without taking the radiator apart.

In carrying out my invention I employ an outer and an inner drum with anannular space between them. The inner drum is shorter than the outerone, but has tubular projections at each end, which extend through thetop and bottom of the outer drum. The inner drum is adapted to rotatewithin the outer drum about a vertical axis and is provided at its upperend with a handle for turning it. Vertical plates or scrapers areattached to the outer drum, and similar vertical plates or scrapers areattached to the inner drum, the arrangement being such that when theinner drum is turned about its vertical axis these scrapers will removefrom the walls of the drum any soot which may have collected upon them.The soot thus detached falls to the bottom of the outer drum and may beremoved through an opening therein.

In the accompanying drawings, Figure 1 shows a front elevation of astove and a vertical central section through my improved radiator. Fig.2 shows a transverse section on the line 2 2 of Fig. 1. Fig. 3 is aperspective View of the radiator withone-half of the outer drum removed.

The stove A is of ordinary construction and has attached to it a pipe B,through which the smoke and other products of combustion pass dated July12, 1904.

to the radiator O. This radiator consists of an outer drum 0, having adetachable connection at D with the smoke-pipe B, and having aconnection at E with a smoke-pipe F, which may pass to the chimney. Theinner drum G is located centrally within the outer drum. It is ofconsiderably smaller diameter than the outer drum and is also somewhatshorter, thus leaving an annular space between its outer periphery andthe walls of the outer drum and a space between its upper and lower endsand the upper and lower ends of the outer drum. The inner drum is formedwith tubular projections H H, which extend through openings in the upperand lower ends of the outer drum. A collar I is attached to theprojection H above the top of the outer drum and rests on this top andsuspends the inner drum within the outer one. A similar collar Jisattached to the projection H inside the outer drum and also serves tosupport the inner drum.

K indicates a handle attached to the outer end of the projection H, bymeans of which the inner drum may be rotated.

Tothe inside of the outer drum are attached two vertical plates orscrapers L M, which extend from the bottom of the inner drum to the topof the outer drum, being widened above the top of the inner drum, asindicated in Figs. 1 and 3, so as to fit closely the top of the innerdrum and the periphery of the projection H. These scrapers L M areplaced on diametrically opposite sides of the outer drum. Verticalplates or scrapers N O are attached to the inner drum and extend fromtop to bottom thereof and also extend across the annular space P totheinner surface of the outer drum. The scrapers L M N O overlap in themanner indicated in Fig. 2.

At the lower end of the outer drum an opening Q, is formed, closed by adoor R, which may be provided with any suitable damper S.

The products of combustion pass from the stove A through the pipe B tothe interior of the outer drumat the upper end thereof on one side ofthe partitions L M; They then pass downwardly on one side of thesepartitions to the bottom of the-inner drum, then pass laterally beneaththe inner drum and up on the opposite side of the partitions L M to thesmoke-pipe F. Thence they pass directly to the outer air or to achimney. In this way the products of combustion are made to traverse acircuitous path, which will cause both drums tobecome highly heated.Heat is radiated from the outer drum, and as air may pass through theinterior of the inner drum heat may be derived from the inside of theradiator.

I find that a radiator made in this way largely increases the heat of aroom, and fuel is thus materially economized.

In order to clean the drum, it is only necessary to turn the handle Kone or more times, so as to cause the scrapers N and O to detach thesoot from the inner surface of the outer drum, while the scrapers L andM at the same time detach the soot from the surface of the inner drum.The soot falls to the bottom of the outer drum and may be removedthrough the opening Q.

Heavy foul air will be drawn into the outer drum through the damper S,if this be left open.

The radiator is so constructed that it may be easily put together ortaken apart. The outer drum is detachable from the smokepipes B and F,and when thus detached and when the collar I and handle K are removedthe outer drum may be lifted away from the bottom piece 0 and thuswithdrawn from the inner drum G. Then the inner drum may be lifted offfrom the bottom piece of the outer drum. It is rarely necessary,however, to thus detach the parts, as the drums may be kept clean by thescrapers, which are operated from the outside in the manner beforedescribed.

My improved radiator while eiiicient is simple and may be made at smallcost and requires little repair.

I claim as my invention 1. In a heat-radiator, the combination with anouter drum having entrance and exit ports, an inner drum of smallerdiameter mounted within the outer drum and rotatable therein, scrapersdividing the space between the drums into two chambers one of whichcommunicates with the entrance-port and the other with the exhaust-portand which connect with each other at that end of the drums opposite theentrance-port.

2'. In a heat-radiator, the combination of an outer drum having entranceand exit ports, an inner drum of smaller diameter mounted within theouter drum and rotatable therein, scrapers secured to opposite sides ofthe outer drum and dividing the space between the drums into twochambers, one of which communicates with the entrance-port and the otherwith the exit-port and which connect with each other at that end of thedrums opposite the entrance-port, and scrapers secured to the inner drumand cooperating with the firstmentioned scrapers to clean the walls ofthe drums.

3. In a heat-radiator, the combination of an outer drum having entranceand exhaust ports, an inner drum of smaller diameter rotatable about avertical axis and open from top to bottom to allow air to pass throughit, scrapers radiating laterally from theinner drum dividing the spacebetween the drum into separate chambers and engaging the walls of theouter drum, a communication between said chambers at that end of thedrums opposite the entrance-port and scrapers attached to the walls ofthe outer drum engaging the inner drum.

4. A heat radiator, comprising an outer drum, an inner drum of lessdiameter than the outer drum, and of less length than said outer drum,tubular projections from the opposite ends of the inner drum whichproject through the top and bottom of the outer drum, a handle attachedto the top tubular projection outside the outer drum. scrapers radiatingfrom the inner drum and engaging the walls of the outer drum, andscrapers attached to the outer drum and engaging the vertical surface ofthe inner drum and the upper tubular projection thereof.

In testimony whereof I have hereunto subscribed my name.
